Scientists at the University of California, Davis, are using ultrasound to find out whether abalone are ready to reproduce.
This non-invasive, no-contact method is kinder than the normal method of getting the info, which involves having to pry them off the surface they are suctioned upon.
Dive! Tutukaka posted the following on their Facebook page.
"Jeroen Jongejans, owner and founder of Dive! Tutukaka passed away suddenly last night. He was on the water, in his happy place - paddle boarding in Tūtūkākā Harbour. We are all struggling to come to terms with this loss.
A spokesman for the Department of Conservation (DoC) stated ''We in the conservation world in Northland are deeply feeling the loss of Jeroen. He was a long-term active member and chair of the Northland Conservation Board and was a passionate advocate for the Poor Knights Marine Reserve, actively promoting its uniqueness and conservation value from its creation, to this day,'' DoC said in a statement.
"Where can I begin… Tutukaka, lost one of most shining stars, a true legend, that I had the pleasure to work for, for four years. A great entrepreneur, who create Dive! Tutukaka, one of the biggest and most efficient company in south hemisphere, a marine reserve, (that know working in Hawaii I See how right he is), two sunken war ships that created a massive artificial reef along TuUkaka coast, and many others great things.
It will be the 16th year in running for MIDE, billed as the “hottest and coolest dive show in Malaysia,” bringing together dive enthusiasts to explore the underwater world and participate in the business of diving as well. Aiming to be a one-stop hub for all things diving, including dive equipment, courses, travel, and underwater conservation, as well as boating and water sports, MIDE promises to showcase all kinds of products and services over the three-day event.
The National Diving & Activity Centre is based at a large flooded quarry in Tidenham, Gloucestershire, England. This dive site is located on the English / Welsh border at Chepstow, just a few minutes' drive from the M48 Severn Bridge. For 52 years, this was a toll bridge - cars would pay £5.60 to cross the River Severn. When bridge tolls were scrapped on 17 December 2018, NDAC suddenly became financially more attractive to dive.
NDAC is permanently closed. We are not taking bookings for leisure activities or public diving.
Divers have asked NDAC about membership refunds. Ashley Bryce, NDAC Manager responded stating that all memberships had been extended by seven months to account for the Covid-19 lockdown.
At the time of writing this, it is not known what will happen to NDAC. Rumours have been circulating for a number of weeks that the Ministry of Defence has bought this dive site. This is unlikely. There are other rumours that the quarry is going to be developed into a holiday park. Whether recreational and technical divers will be able to access and dive these unique waters again, is not known at this point.
In the new six-part podcast, Into the Depths, Roberts tells of her time with a group of Black divers whose mission is to locate and help document the wrecks.

We asked our contributors what their favorite black-and-white underwater photographs were, and they came back with diverse and dramatic images and stories captured under the waves.
When it comes to responding to certain computer alarms, can one be too cautious? Being well informed about gas exposure limits and computer defaults can be an advantage. Simon Pridmore discusses a case in point, involving computer nitrox alarms on a routine wreck dive
Advanced Ocean Diver (AOD) is an optional course that gives new divers more choice and flexibility as they progress with their training.
The course is open to all Ocean Divers (or divers who have an equivalent certification from another recognised diver training agency and have also completed Nitrox training) aged 14 and over.
The Advanced Ocean Diver course includes four theory sessions, which can be completed either via eLearning or in person with an instructor, giving flexibility for students and instructors.
Some ocean animals are just inspiring. To be able to glimpse a massive animal like a whale shark can be a lifelong dream that some divers never get to experience. The ocean’s largest living fish inhabits all of the world’s tropical waters, but sightings are usually rare. However, there are a few seasonal hot spots where the likelihood increases.

The first time I went cave diving in Mexico's Yucatán was over 22 years ago. I will never forget how excited I got, swimming through these spectacular passages. I remember thinking this was as close to being on another planet as I would ever get.
